Despite the Swiss-born socialite being awarded $2.5 billion (Â£1.7 billion) from her former elite art dealer and horse-racing husband, Alec, in the late 1990s in one of the biggest divorce settlements in history, she claimed in the past week that she's broke.
DNA structure. DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).The order of these bases is what determines DNA's instructions, or genetic code.ach nucleotide contains a phosphate group, a sugar group and a nitrogen base.

Today, this molecule is called DNA. Nearly all of the cells within a single organism include exactly the same DNA. DNA is a linear molecule composed of four types of smaller chemical molecules called nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T).The order of these bases is called the DNA sequence.n 1953, Francis Crick and James Watson described the molecular shape of DNA as a double helix.. Double-stranded DNA is composed of two linear strands that run opposite to each other, known as anti-parallel strands; these strands twist together to form a double helix.
